IMPROVEMENTIN MACHINES FOR FILLING BARRELS.

The Schedule referred to in these Letters Patent; and making part of the same.

I, JOHN L. STEWART, of the city and county oi' Philadelphia, and State ot' Pennsylvania, have invented an Improved fMachiue for Filling Barrels, of which the following is a specication.

The object of my invention is to construct a selfacting mechanism, by which the cock which supplies liquid to the barrel is closed as soon as the barrel is suiiioiently iiled.

To enable others skilled in the art to make and use my invention I will lproceed to describe its construc- .ton and operation, reference being had to the accompanying drawing, in which- Figure l is a plan.

Figure 2 is an elevation of the apparatus, partly in section'.

A is the pipe leading from the tank of v'oil or other liquid.

B is the supply-cock, the lever of which, W, is operated by a spring, S, on one side, anda trigger arrangement on the other.

The cock B is connected by a short p ipe to the elbow D, which contains the mechanism for operating the trigger.

This elbow terminates in a spigot, E, made to enter the bung-hole of the barrel.

A screw is cut upon the spigot, upon which tits the conical collar F, having a handle, f', by' which its position can be adjusted upon the spigot so as to regulate to exactness the amount of liquid to be let into the barilel.

The collar F has a screw upon the cone, so that, by

one or two turns of the handle f', the cone is made air-tight in the bung-hole.

An air-passage, G, is cast in this elbow, the lower end openinginto the barrel, the upper end terminating in a chamber, H, open to the atmosphere.

This chamber has a dividing plate, It', castin, hanging from the top nearly to the bottom ofthe chamber.

Another air-pipe, K, opens into the barrel about an inch above the opening G, the upper end terminating -in a chamber, M, closed by a leather or similarly flexible diaphragm, N.

To this diaphragm is attached a rod, U, passing through an adjustable nut, p', screwed into the cap P. A support, R, is 'screwed into the elbow D, to which is hinged the forked trigger T by a pin, t.

A connect-ing-link,` FV, is jointed to trigger T by pin t, and, at the other end, is jointed to arm lV by pin w.

While the barrel is being filled the trigger is in position shown vin fig. 2, the pins t', o', and w' being in a straight line. When the eocli is shut it takes the position of dotted lines t. The triggeris adjusted toits proper sensitive point by screw p.

The machine operates in this way:

The spigot is placed in the bung-hole, and one or two turns made with the handle j', so as to close the bung-hole tight. n

The trigger is pressed upon the sorewp, the cock being thus opened, and the barrel begins to iiil.

When the liquid rises to the level of the opening G the exit of air from the barrel is stopped, and is, consequently, compressed up the tube li into the chamber 'M, raising the diaphragm N and tapping oil" trigger T, and closing the cock B. Just as the bar l rel is iull the liquid would spurt out of the top ofthe passage G wasv it not for the plate h'retarding it and causing it to ret-urn to the barrel.

I do not restrict myself to the cock here shown, as a puppet-valve might be connected to the trigger arrangement by means of a bell-crank.

lVhatI claim as my inventioiuand desire to secure by Letters Patent, is-

l. The trigger arrangement,consisting of trigger T, link V, and spring S, so set that the joints c', t',

` and w' are in the same straight liuc, and operating the valve B, in the mannerherein described.

2. The elastic diaphragm N, within the chamber M, arranged, in combination withl the air-passage K and spigot E, so that the compressed air at the top of the barrel operates the diaphragm, i'or thc purpose herein described.

3. The combination ofthe diaphragm N, rod O, nut p, and trigger T, i'or the purpose herein shown and described.

4. The adjustable conical stopper j", screwed in ternally upon the spigot E, to regulate the quantity of oil admitted to the barrel, and screwed externally to make an air-tight joint, substantially as described.
